i'm also not so sure it works that easily through an LCM. don't you have to have the coils on top ? so that would mean to put them into the glass or some have transparent plastic circuit above the display

and i don't think most studios will be very interested in anything that's not 1080p and so on. there's always the tendency to use the best technology available, to be able to reuse the material in a few years

for vision, how about a camera pixel path element that "listens" to an NxM matrix in the pixel stream. for each pixel, it differentiates, does a bandpass filter, followed by a per-pixel hysteresis and maybe an overall quorum. that would then become a signal to the LM32 and from there it could go into a PFPU variable
